Overview
The TS4962IQT is a single-channel Class-D BTL audio power amplifier manufactured by STMicroelectronics. It operates from a supply voltage range of 2.4 V to 5.5 V and delivers up to 2.8 W into a 4 Ω load with 10% THD+N at 5 V, or 2.2 W with 1% THD+N. The device features a PWM base frequency of 360 kHz, typical efficiency of 88%, and signal-to-noise ratio of 85 dB. It is housed in an 8-pin DFN package measuring 3 mm x 3 mm x 0.88 mm, suitable for surface mount installation within an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates active low standby mode reducing current consumption to 10 nA typical.
- Includes pop and click reduction circuitry for low on/off switch noise.
- Features adjustable gain controlled via two external resistors.
Applications
- Automotive audio systems
- Portable speaker applications
- Consumer electronics requiring high-efficiency amplification
Procurement Notes
Verify the specific suffix 'QT' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component grade matches the required industrial temperature range. Cross-reference the ordering part number with the latest STMicroelectronics documentation to avoid discrepancies in pinout or electrical characteristics due to product revisions.
Selection Notes
Select this component for designs requiring a filter-free Class-D solution with low quiescent current. It is appropriate for battery-powered devices where efficiency is critical. Verify that the load impedance and supply voltage align with the specified output power curves. Consider the thermal performance of the DFN package for the intended enclosure environment.
Part Context
This part belongs to the TS4962 family of differential Class-D BTL power amplifiers. The series is designed to replace traditional Class-AB amplifiers by offering significantly higher efficiency while maintaining audio quality. The TS4962IQT variant specifically denotes the industrial temperature grade and the DFN8 packaging configuration.
Replacement Considerations
The TS4962MEIJT is a documented alternative within the same family, utilizing a 9-ball Flip Chip package instead of DFN. Verify pin compatibility and thermal dissipation requirements when substituting between these package types.
